Expert repair, installation, maintenance, and replacement for commercial air conditioning, heating, and rooftop package unit systems. Serving businesses across Aubrey, Frisco, McKinney, Plano, and all of North Texas — including full crane-assisted RTU installations.
A commercial HVAC system that fails during a Texas summer or an unexpected winter freeze doesn't just make your facility uncomfortable — it disrupts operations, drives away customers, and in some environments creates safety or compliance issues. Rock Hard Refrigeration provides commercial HVAC services designed to keep your business running regardless of what the weather does.
We service all types of commercial HVAC systems — rooftop package units, split systems, commercial air handlers, commercial furnaces, heat pumps, and mini-splits. Our HVAC license (TACLA113168C) covers the full scope of commercial heating and cooling work, and our technicians bring the same commercial-focused expertise to every HVAC job that defines our refrigeration work.
From a failed RTU on a 105°F August afternoon to a crane-assisted new unit installation coordinated across multiple trades, Rock Hard handles commercial HVAC at every scale for businesses throughout North Texas.
Full repair, installation, maintenance, and replacement — commercial grade, all major brands.
Rooftop package units are the workhorse of commercial HVAC in North Texas. Most retail centers, restaurants, office buildings, and industrial facilities rely on RTUs to heat and cool their space. When an RTU fails, the entire zone it serves goes down — and in Texas summers, that means a business that can't operate.
Rock Hard technicians work on commercial RTUs every week. We service all major brands, carry OEM parts for common RTU failures, and respond to RTU emergencies with the urgency a down commercial system requires.
All major makes and models — licensed technicians, OEM parts, North Texas coverage.
Replacing a commercial rooftop package unit is a major undertaking. Large RTUs can weigh several thousand pounds and require crane equipment, rigging expertise, and a coordinated crew to safely lift and set on a commercial rooftop curb.
Rock Hard Refrigeration manages the complete RTU replacement process — equipment selection, crane coordination, disconnection and removal of the old unit, installation of the new unit, refrigerant charging, electrical hookup, controls setup, and full performance verification before handover.
We service and stock OEM parts for all major commercial HVAC brands.
